Panel Creation

For cost-saving or technical reasons (such as improved assembly), multiple circuit boards may be combined to form one large board, a “panel”. This panel is then produced just as a single large circuit board. A separation of the panel does not occur!

Always consult with your assembly partner about the panel design; take note of (for example) fiducial marks and capture holes! A damaged circuit board (according to E-test) will not be removed from the panel, but rather marked. This must be observed during assembly.

Panel types:

Multiplier: The same circuit board repeated in the panel

Mixed Multiplier: Different circuit boards composed into the panel

Mechanical processing

Scoring

Milling with bridges to break out (IMPORTANT: 2.0mm or 10mm spacing, see below!)

Mixed multiplier panels

For complex panels, multiple different circuit board layouts can be composed onto one panel. The completed panel is scored, or partially milled, to provided the contained PCBs with bridges for breaking out.

Mixed multiplier scored

When designing the panel, please observe that a spacing of 0.0mm is left between the circuit boards.

The contour line thickness should be 0.01mm / 1 mil.

Because of the tolerances when breaking out the individual circuit boards, all conductor traces and copper areas should have a spacing of at least 500µm from the scoring edge (see scoring).

We recommend using scoring technology only for panels with a circuit board thickness of at least 1mm (stability).
